Unpolarised light of intensity I passes ...

Unpolarised light of intensity I passes through an ideal polariser A. Another identical polariser B is placed behind A. The intensity of light beyond B is found to be `(I)/(2)`. Now another identical polariser C is placed between A and B. The intensity beyond B is now found to be `(I)/(8)` . the angle between polariser A and C is
